My old passport expired and I got a new one. My old passport has my electronic visa in Australia. I know I can cancel my visa at the immigration office.

Australian e-visa is closely related to your passport number. Therefore, if you change your passport, according to the requirements of the Australian Immigration Bureau, you need to associate this old existing visa with the new passport. That is to associate this new passport number with this existing old visa. If you don't comply with this requirement, you may be refused entry. Link doesn't have a valid Australian visa because it is a new passport.

It is suggested that the landlord should do a good job of visa association before leaving for Australia. I don't know which jurisdiction you are in. Australia now has visa centers in Beijing, Shanghai, Guangzhou and Chengdu. It should be more convenient if you can go directly to the visa center in your jurisdiction to handle visa transfer. You need to fill in the 929 form, which can be downloaded directly from the Australian Visa Center.

I wish you a smooth life in Australia.
